Brushed Surface Pot Base Aluminum Circle

Core Advantages

• Uniform continuous hairline brushed texture, matte metal appearance, hide minor scratches, reduce obvious fingerprint residue

• Outstanding thermal conductivity, guarantee uniform heat spread for pot base, avoid local over‑heating

• 3003 alloy option provides better rigidity & dent‑resistance, anti‑deformation after long‑time high‑temperature heating

• Clean surface without oil spot, black stain; perfect for composite bonding with stainless steel induction layer

• Burr‑free trimmed edge, stable dimension tolerance, fit automatic cookware composite pressing production lin

• Food‑contact safe raw material, meet LFGB / FDA requirement for kitchen cookware

• Surface can be protected by PE film to avoid scratch during transportation and secondary processing

• Support custom brushed grain thickness: fine hairline / coarse hairline according to customer demand

Production Process

Aluminum coil uncoiling → Leveling & degreasing cleaning → Mechanical sand‑belt hairline brushing → Surface cleaning & chip removing → Annealing treatment → High‑speed blanking into round circles → Deburr edge treatment → Brushed surface visual inspection → Flatness test → PE protective film pasting → Separated by interleaving paper → Export packaging Each batch inspects dimension, brushed surface uniformity, flatness and bonding performance for composite pot base before delivery.

Technical Parameters

Application

Household cookware: Frying pan bottom, sauce pot base, wok bottom, milk pot composite base Induction cookware: Aluminum intermediate layer for stainless‑aluminum composite induction pot base Commercial kitchen: Large‑size restaurant cookware bottom, heavy‑duty cooking pan substrate Cookware processing factory: Raw blanks for multi‑layer bonded pots, pressure‑cooker bottom

Loaded on IPPC fumigated wooden pallets, fastened with packing straps. Shipping marks mark alloy grade, temper, thickness, diameter, grain type(fine/coarse hairline), net weight, gross weight and batch number. MTC, food‑contact safety report and fumigation certificate can be provided for customs clearance and cookware factory incoming inspection.

FAQ

Q1: What alloy is most recommended for brushed pot‑base aluminum circle? A: 3003‑H24 is the top choice for pot base, higher strength, anti‑deformation under high temperature; 1060 for cost‑effective light‑weight cookware.

Q2: Fine hairline or coarse hairline brushed? A: Fine hairline is mainstream for high‑end cookware pot base; coarse hairline for heavy‑duty commercial cookware.

Q3: Can this brushed circle be compound‑bonded with stainless steel for induction base? A: Yes, surface is clean without residual abrasive, perfect for roll‑bonding / hot‑press composite process.

Q4: Is the brushed surface food‑safe? A: Mechanical brushing without chemical coating, raw material meets food‑contact standard for kitchen utensils.

Q5: What thickness is commonly used for cookware pot base? A: 2.0‑4.0mm for household pots; 4.0‑6.0mm for heavy‑duty commercial cookware.
